Session 86 - Cosmology: Theory.
Display session, Friday, January 09
Exhibit Hall,
We investigate the statistical properties of structures transverse to the line of sight which appear in theoretical N-body simulations of structure formation, and also to be present in observational data from redshift surveys. We present a simple statistic which can quantify this effect in a conceptually different way from standard analyses of distortions of the power-spectrum or correlation function. From tests with N--body experiments, we argue that it represents a new and potentially powerful diagnostic of the cosmological density parameter, Ømega.
